Method Details

init

public boolean init(Expression<?>[] expressions,
 int matchedPattern,
 ParseContext parseContext)

Description copied from interface: SyntaxElement

Initializes this SyntaxElement before being used. This method is always called before all the others in an extending class, the only exception being CodeSection.loadSection(FileSection, ParserState, SkriptLogger).

Specified by:

init in interface SyntaxElement

Parameters:

expressions - an array of expressions representing all the expressions that are being passed to this syntax element. As opposed to Skript, elements of this array can't be null.

matchedPattern - the index of the pattern that was successfully matched. It corresponds to the order of the syntaxes in registration

parseContext - an object containing additional information about the parsing of this syntax element, like regex matches and parse marks

Returns:

true if the syntax element was initialized successfully, false otherwise.

getValues

public Object[] getValues(TriggerContext ctx)

Description copied from interface: Expression

Retrieves all values of this Expression, accounting for possible modifiers. This means that if this is an or-list, it will choose a random value to return.

Specified by:

getValues in interface Expression<Object>

Parameters:

ctx - the event

Returns:

an array of the values

See Also:

• Expression.getArray(TriggerContext)

isSingle

public boolean isSingle()

Specified by:

isSingle in interface Expression<Object>

Returns:

whether this expression returns a single value. By default, this is defined on registration, but it can be overridden.

getReturnType

public Class<?> getReturnType()

Specified by:

getReturnType in interface Expression<Object>

Returns:

the return type of this expression. By default, this is defined on registration, but, like Expression.isSingle(), can be overriden.

toString

public String toString(TriggerContext ctx,
 boolean debug)

Specified by:

toString in interface SyntaxElement

Parameters:

ctx - the event

debug - whether to show additional information or not

Returns:

a String that should aim to resemble what is written in the script as closely as possible
